L_P_ Approximation By Relu Neural Networks, Eman Samir Bhaya, Zainab Abdulmunim Sharba

Karbala International Journal of Modern Science

We know that we can use the neural networks for the approximation of functions for many types of activation functions. Here, we treat only neural networks with simple and particular activation function called rectified linear units (ReLU). The main aim of this paper is to introduce a type of constructive universal approximation theorem and estimate the error of the universal approximation. We will obtain optimal approximation if we have a basis independent of the target function. We prove a type of Debao Chen's theorem for approximation.

Florida University (1883), C. L. Crow

Florida Historical Quarterly

The most ambitious and most visionary attempt ever made to establish in Florida an institution of higher learning was probably that of the founders, or founder, of Florida University. The plan of organization of the proposed school, altho not successfully carried out, was nevertheless worthy of some respect, for Dr. Kost, its main proponent, had perhaps a vision similar in part to that which afterward inspired Mr. Buckman.

Teacher Retention In A Rural East Texas School District, Gary J. Miller

School Leadership Review

This qualitative study investigated what factors kept teachers committed to teaching in one rural east Texas school district despite the perceived educational inequalities of rural districts compared to suburban and urban districts. When it comes to teacher retention, rural school leaders cite school environment and community lifestyle compatibility as the primary reasons for staying. Despite the considerable number of rural school districts throughout the United States, research continues to largely ignore the unique relationships found in rural locales. Rural school districts offer many advantages over their suburban and urban counterparts; it is a matter of identifying what is important to …

Principals demonstrated that while it is paramount to set organizational structures and policies conducive …

Talk Or Walk: School Principals And Shared Instructional Leadership, Sheila Baker, John Decman, Jana M. Willis

School Leadership Review

Beginning in March of 2020, public school educators at all levels were thrown into a situation in which they were required to drastically alter pedagogical approaches to teaching and learning. The move from classroom-based instruction to a virtual platform, whether synchronous or not, was too often done on-the-fly and with mixed results. With the realization and acceptance, albeit grudgingly, that web-based, internet-based, and/or virtual platforms need to be greatly expanded to the population and may become the norm for public education, there clearly exists a need for an expanded definition of instructional leadership.

The purpose of this study is to …

Personal Reflections / 12.14.20, José M. Torres

Personal Reflections

On Saturday, December 7, 2020, I got up early at 5:00 a.m., put on a white shirt, a black jacket, and shorts, and joined a zoom call broadcasted from Alexandria, Egypt. A longtime friend, Bill, passed away at age 90 from COVID-19 complications. Bill and his wife Peg, who passed away 12 years ago, opened their home to me in 1980, when I was only 20 years old and needed a place to stay. Six months later, I found a more permanent home. While my time living with them in their home was short, this experience and our continued relationship …

Creating Authentic Literacy Tasks Influences Children's Engagement And Motivation, Carly Rothfusz

Innovations and Critical Issues in Teaching and Learning

The academic task assigned to students often dictates what the student will learn, and it plays a vital role of student’s motivation and engagement of learning (Turner & Paris, 1995). Thus, the creation and usage of authentic literacy tasks is critical for students’ learning (Parsons, Malloy, Parsons, & Burrowbridge, 2015). There are three types of motivation to consider: intrinsic motivation, extrinsic motivation, and autonomous motivation. The use of authenticity, student choice, collaboration, and challenge are all components within a task that can promote student engagement and motivation. Project-Based Learning (PBL) is another way to bring in authenticity. Project-based instruction allows …

Modeling Combustion Of Straw-Bitumen-Pellets In A Fluidized Bed., Farouk Okasha

Mansoura Engineering Journal

Recently straw-bitumen-pellets have been proposed as an alternative fuel. This work presents a mathematical model for steady state combustion of straw-bitumen-pellets in a bubbling fluidized bed. The combustor is divided into three zones; dense bed, splashing zone and freeboard. Important processes including volatile segregation, char comminution and elutriation, bed particles ejection; and post-combustion in splashing zone and freeboard have been considered and simplified. Submodels for hydrodynamic, volatile release and combustion, and char consumption have been implemented. Energy balance for splashing zone and freeboard has been set to predict axial temperature profile. Model results demonstrate that about 53% of volatiles combustion …
